題目

本文將設(shè)計一個飛機訂票系統(tǒng)，主要包括機票的添加、修改、查找、訂票、退票、推薦機票功能，用C語言編程實現(xiàn)，并用鏈表存儲產(chǎn)生的航班信息和訂票信息數(shù)據(jù)，最后可以把鏈表中的數(shù)據(jù)保存到文件中。

總體設(shè)計和需求分析

設(shè)計目的

1.怎樣去合理的設(shè)計一個數(shù)據(jù)結(jié)構(gòu)來存儲訂票信息和航班信息
2.加深對鏈表的增刪改查功能的學習和理解
3.學習如何鏈表和外部文件之間的讀取和存儲操作
4.學習如何將學到的知識應(yīng)用到實際的問題中

總體設(shè)計和功能

此飛機訂票系統(tǒng)將實現(xiàn)以下功能：
1.初始化功能
??該功能將實現(xiàn)將航班信息文件和訂票人訂票信息文件中的數(shù)據(jù)讀取到鏈表中。
2.添加機票信息功能
??該功能將實現(xiàn)添加航班機票信息，信息包括航班號、出發(fā)地、目的地、起飛時間、降落時間、票價、折扣、剩余票數(shù)，然后用鏈表將數(shù)據(jù)保存起來。
3.查詢機票信息功能
??該功能將實現(xiàn)通過航班號來查詢機票信息的功能
4.修改機票信息功能
??該功能將通過航班號調(diào)用查找機票信息功能，定位到要修改的航班信息上，然后通過航班信息子菜單確定要修改的某一項航班信息。
5.顯示機票信息
??該功能將實現(xiàn)把所有航班信息顯示出來
7.推薦機票功能
??該功能將實現(xiàn)通過輸入目的地，和乘客最早出發(fā)時間可以獲得符合條件的航班信息
8.訂票功能
??該功能下乘客輸入目的地，并且輸入訂票人的姓名、身份證號碼、性別、購票數(shù)量、訂購航班號以實現(xiàn)用戶訂票功能
9.退票功能
??該功能下乘客可以訂購的機票進行退回。
10.顯示時間功能
??該功能可以顯示實時時間
11.保存信息功能
該功能下可以把鏈表中的信息保存到文件中。

結(jié)構(gòu)體設(shè)計

我們將定義兩個結(jié)構(gòu)體，分別為機票信息結(jié)構(gòu)體和訂票人信息結(jié)構(gòu)體

機票信息結(jié)構(gòu)體

typedef struct AirPlane {char acFlight[20];//航班號char acOrigin[10]; //出發(fā)地char acDest[20]; //目的地char acTakeOffTime[10]; //起飛時間char acReverceTime[10]; //降落時間float fPrice; //票價char acDisscount[4]; //折扣int iNum; //剩余票數(shù) }AirPlane, * PAirPlane; //定義機票信息節(jié)點的結(jié)構(gòu)體 typedef struct PlaneNode {struct AirPlane stDate;struct PlaneNode* pstNext;}PlaneNode, * PPlaneNode;

訂票人信息結(jié)構(gòu)體

typedef struct Man {char acName[20]; //姓名char acID[20]; //身份證號碼char acSex[10]; //性別 int iBookNum; //購票數(shù)量char acBookFilght[10]; //訂購航班號 }Man, * PMan; //訂票人信息節(jié)點的結(jié)構(gòu)體 typedef struct ManNode {struct Man stDate;struct ManNode* pstNext; }ManNode, * PManNode;

主函數(shù)的設(shè)計

在主函數(shù)中，首先將通過初始化函數(shù)把文件中的數(shù)據(jù)讀取到鏈表中，然后可以通過switch選擇用戶在飛機訂票系統(tǒng)中需要執(zhí)行的操作

//作為數(shù)據(jù)改動的標志 int iSave = 0;int main() {struct PlaneNode pstPlaneNodeHead; //機票信息頭結(jié)點pstPlaneNodeHead.pstNext = NULL;struct ManNode pstManNodeHead; //購票信息頭結(jié)點pstManNodeHead.pstNext = NULL;Init(&pstPlaneNodeHead, &pstManNodeHead); // 將文件的數(shù)據(jù)加載到內(nèi)存中int iSel = 0; //用于接收用戶對功能的選擇char c1;while (1){system("cls");Menu();printf("Input 0-9 operations:");scanf_s("%d", &iSel);getchar();switch (iSel){case 1:printf("進入添加機票頁面\n");Insert(&pstPlaneNodeHead); // 添加機票信息break;case 2:Search(&pstPlaneNodeHead); //查詢機票信息break;case 3:Book(&pstPlaneNodeHead, &pstManNodeHead);//訂票break;case 4:Modify(&pstPlaneNodeHead); //修改機票信息break;case 5:Show(&pstPlaneNodeHead); //顯示機票信息 break;case 6:Recommend(&pstPlaneNodeHead); //推薦機票信息break;case 7:Refund(&pstPlaneNodeHead, &pstManNodeHead);//退票信息break;case 8:NowTime();//顯示當前時間break;case 9:SaveMan(&pstManNodeHead); //數(shù)據(jù)保存SavePlane(&pstPlaneNodeHead);break;case 0:if (iSave == 1){printf("do you want to save (y/n)");scanf("%c", &c1);getchar();if (c1 == 'y' || c1 == 'Y'){SaveMan(&pstManNodeHead); //保存訂票人的信息SavePlane(&pstPlaneNodeHead); // 保存機票信息}}Destroy(&pstPlaneNodeHead, &pstManNodeHead);return 0;}printf("\nplease press any key to continue...\n");_getch();}Destroy(&pstPlaneNodeHead, &pstManNodeHead);return 0; }

各功能代碼的實現(xiàn)

前置

寫入需要用到的頭文件、宏定義以及其中的打印函數(shù)等等

顯示時間

測試

先進行添加機票功能的測試
將添加機票信息輸入完整，然后輸入-1返回主菜單
然后對查詢機票功能進行測試，輸入剛剛添加的航班號，可以看出已經(jīng)查詢到新添加的機票信息
然后對修改機票信息功能進行測試，我們將目的地修改為beijing

然后返回主菜單，測試顯示所有機票信息的功能

可以看出已經(jīng)成功把1005號航班的目的地修改為beijing
對推薦機票功能進行測試
選擇你要去的地方和你最早可以到達時間，然后會打印符合條件的機票信息

然后對訂票功能進行測試

然后對退票功能進行測試，通過ID可以定位到剛剛訂票的信息，然后選擇退票
